This invention relates to weft carriers for weft replenishing looms wherein a fresh sup ply of weft is furnished the shuttle from time to time during the loom operation.

5 It is now the usual practice to provide weft replenishing looms with a hopper or magazine for the support of the weft carriers and their movement to transferring position. In looms of this type it isessential that the shuttle be automatically threaded as the shuttle is picked, and it has been the practice for the waver to find the end of the weft, unwind it from the carrier and secure it to a fixed point which has been generally constituted as a stud at the end of the hopper. As a consequence of securing the end of the weft as stated the shuttle becomes partially threaded on the first pick following replenishment.

Since the weaver is called upon to find the end of the weft on the wound carrier as he places the carriers in the hopper or magazine, much valuable time is lost in finding the end of the weft because it clings tightly to the wound surface as it comes from the spinning frame. One of the objects of the present invention is to facilitate the weavers worlr as he places the filled carriers in the hopper or magazine and grasps the weft end to secure it to the weft end stud to insure shuttle threading.

In accordance with the present invention the weft carrier is provided with a weft end holder formed as a spring which may clamp the weft end against the tip portion of the carrier with the result that as the weaver withdraws the projecting end of the weft for attachment to the weft end stud, the weft end holder will be grasped by the weaver and re moved longitudinally of the weft carrier, so

to that the weft carrier may be readily placed in the magazine or hopper freed from the weft end holder.

The work of finding the weft end and clamping it to the tip of the weft carrier by means of the weft end holder may be readily accomplished at a point remote from the loom and by cheap labor, with the result that the work of the weaver and cost of cloth production are materially reduced.

In accordance with the present invention tip of the weft carrier and clamping the pro- 1329. Serial No. 352,291.

he weft end holder is constituted as a spring of somewhat less diameter than the tip of the weft carrier and is provided with an opening at one side whereby it may be applied over the tip of the weft carrier in a transverse direction and thus clamp or secure the weft end ready for the weavers manipulation.

The invention and novel features thereof will best be made clear from the following description and accompanying drawings of one good practical form thereof.

In the drawings Fig. 1 is a perspective view of a hopper or magazine showing more particularly how the wearer may manipulate and withdraw the weft end from the weft carrier as he also removes the weft end holder.

Fig. 2 shows a weft carrier wound with weft and the end of the weft drawn endwise of the weft carrier, with the weft end holder positioned. for application to the tip of the weft carrier.

Fig. 3 is a View similar to that of Fig. 2 but showing the weft end holder in place on the jecting end of the weft ready to be grasped by the weaver.

The hopper or magazine for holding the fresh supplies of weft may be of usual type and as herein shown consists of a stand 1 30 mounted upon the loom frame as usual and supporting the rotary hopper which may consist of the disk 2 for holding the head portions of the weft carriers, and a somewhat similar disk 3 for holding the tip end portions of the weft carriers.

The stand 1 has extending therefrom the stud l on which is mounted the transferrer 5 normally under the influence of a spring 6 for maintaining it in upward or inactive position. and extending from the hub portion of the transferrer is the arm 7 to which may be pivoted at 8 the transferrer dog 9, herein shown as engaged with a hunter 10 on the lay 11, for imparting to the transferrer its transferring n1ove1nent as usual in this class of looms.

The rotary hopper has a supporting stud or shaft 12 on which is mounted the weft end stud 13 to which the weft ends are'secured by 109 the weaver as he fills the hopper or magazine with a fresh supply of weft carriers. As usual in this class of hoppers or magazines, there may be the guides 14 for directing the weft ends of the weft carriers in the hopper or magazine.

The weft carrier consists of a barrel portion as usual having 'a head 15 which may be supplied with the rings 16 for detachable en gagement with the bobbin holding springs in the shuttle. hen the weft carrier is supplied with weft, as indicated at 17, and comes from the spinning frame, the weft end is carried spirally about the wound weft and clings closely thereto so that much difiiculty is experienced and loss of time and expense incurred when the weaver himself tries to find the weft end to attach it to the weft end stud in the hopper. I

A wound weft carrier, as indicated in Figs. and has the weft wound thereon in conical layers which have been gradually laid towards the tip end portion of the weft carrier leavingan exposed tip 18, and, in accordance with the pr .ent invention, th weft end holder constituted as a spring 19 of general circular form having a side opening 20 of less width than the diameter of the weft carrier tip, with the result that the weft end holder may be applied about the tip and over the withdrawn weft end a which has previously beenfound and extended by the employment of cheap labor and before the weft carrier reaches the loom.

lVhenthe weft end holder is applied to the tip of the weft carrier as indicated in Fig. 3, the springweft end holder clamps the extended end a of the weft upon the surface of the tip and when the weaver receives the weft carriers in the condition indicated in Fig. 3 he may grasp with one hand the wound weft carrier, as indicated at Z), Fig. 1, then grasp by his other hand as 0 both the weft end a and the weft end holder 19, and withdraw both simultaneously lengthwise of the weft carrier.

.Under these conditions it will be apparent that the weaver has only to grasp the weft carrier with one hand and the weft end holder the tip portion of the weft carrier, with, the

result that the spring action of the weft end holder serves not only to maintain it on the tip of the carrier, but also to yieldingly clamp the withdrawn end a of the weft.

It is desirable that the weft end. holder 19 shall not only have the, opening 20 in its side. but that, theterminalnortions of the weft end holder 19 as at 21 and 22 be flared outwardly so that the weft end holder may be readily applied about the tip of the weft carrier and over the withdrawn weft end a.

Claims 1. A weft carrier for weft replenishing looms having a head portion and a tip, and a. weft end holder constituted as a curved spring; having a side opening of less width than the tip diameter that the holder may be transversely applied about the tip and over the weft end and manually removed endwise of the tipas the weft end is withdrawn for attachment to a fixed part.

2. A weft carrier for weft replenishing looms having a head portion and a tip, and a weft end holder formed as an open sided curved spring, for clamping the weft end upon the tip and manually removable endwise of the tip as the weft end is withdrawn to be attached to a fixedpart.

A weft carrier having a head portion and a tip to be held in the hopper of a Weft replenishing loom, and a weft end holder constituted as a curved spring of less interior diameter than the diameter of the carrier tip to yieldingly hold the Weft end clamped upon the tip and manually removable endwise of the tip with the weft end as it is withdrawn for attachment to the weft end stud.

In testimony whereof, I have signed my name to this specification.
